Healthy. Comfortable.
Built to perform.

Many New Zealand homes lose significant amounts of heated air through small, uncontrolled gaps in the building envelope.

Airtightness doesn’t mean sealing fresh air out. It means controlling where air enters and leaves the home.

By reducing unwanted air leakage, a high-performance home stays warmer during winter, cooler during summer and requires less energy to maintain comfortable temperatures. Controlled ventilation systems then introduce fresh, filtered air without losing valuable heat.

The result is a healthier, quieter and more energy-efficient home.

Mechanical Heat Recovery Ventilation continuously removes stale indoor air while supplying filtered fresh outdoor air.

Before the warm indoor air leaves the home, a heat exchanger transfers much of its heat to the incoming fresh air. This means your home receives a constant supply of clean air without losing the warmth you’ve already paid to create.

MHRV systems help reduce condensation, improve indoor air quality, remove excess moisture and create a healthier living environment all year round.

Absoutley.

Open your windows when you want to. Close them when you don’t. Your High performance home keeps breathing either way.

A High Performance Home doesn’t mean your windows stay closed. The difference is that you don’t have to rely on open windows for ventilation. MHRV systems continuously bring in fresh, filtered air and removes the stale air, even when your windows are closed.

Every project is different, so insulation specifications are selected based on the home’s design, orientation, climate and performance goals.

HP Homes carefully considers wall, roof and floor insulation together to create a continuous thermal envelope rather than focusing on individual products alone.

The objective isn’t simply achieving higher R-values. It’s creating a complete building system that delivers long-term comfort, efficiency and durability.

Many existing homes can be significantly improved through targeted upgrades such as improved insulation, higher-performance windows, better ventilation and air-sealing.However, some older homes have structural limitations that make achieving true high-performance standards difficult.

During the planning stage, HP Homes works closely with clients to determine whether renovation or rebuilding provides the better long-term outcome based on performance, cost and lifestyle goals.

Not necessarily.

Passive House certification follows internationally recognised performance standards and can be an excellent option for some projects.

However, many homeowners want the benefits of Passive House principles without formal certification.

HP Homes applies the same building science principles—including airtightness, insulation and balanced ventilation—to create homes that deliver exceptional comfort and efficiency while allowing flexibility in design and construction.

Every household uses energy differently, so savings vary.

However, because high-performance homes lose less heat during winter and gain less heat during summer, they generally require far less energy to maintain comfortable indoor temperatures.

Many homeowners find that lower heating and cooling demand helps offset the initial investment over time while also providing greater comfort and healthier living conditions.

No.

The most appropriate glazing solution depends on climate, orientation, window size and the overall performance objectives of the home.

For some projects, high-quality double glazing provides excellent results.For others, particularly colder alpine environments, triple glazing may offer worthwhile long-term benefits.

HP Homes assesses each project individually to recommend the most appropriate solution.

Construction time depends on the size, complexity and location of each project.

Because greater attention is given to detailing, airtightness and quality control, high-performance homes often require more precision during construction than conventional builds.

The additional care invested during construction contributes to a home that performs better for decades to come.

Yes. MHRV systems continuously bring fresh filtered outdoor air before it enters the home. This reduces airborne particles such as dust and pollen, creating a cleaner, more comfortable indoor environment for people who suffer from asthma and allergies.

Absolutely. The constant supply of fresh filtered air controls moisture and reduces the build up of indoor pollutants. This creates a cleaner, more comfortable indoor environment for everyday family life.
